LONG_LONG_MIN, LONG_LONG_MAX and ULONG_LONG_MAX are GLibc-specific macros that are better defined in <limits.h> instead of the current exotic location (<pthread.h>). Note that GCC's <limits.h> only defines these macros when __GNU_LIBRARY__ is also defined. This is only the case when building against GLibc, so manually redefine the macros here. Note that using LLONG_MIN/LLONG_MAX/ULLONG_MAX is the C99-compliant way to get these values, but it's easier to define these compatibility macros for the sake of porting existing code.
